I listened to them all and I think 'Four Months' is strong as well as 'Prarie Night'. All I can say about your voice is that it's better than mine. You could be Roddy Frame of Aztech Camera. It's got the power and timing, and your phrasing brings out some extra grit which is to say that you're writing to your vocal strengths. I wouldn't have known what you were singing if you hadn't put up the lyrics, but that might be an accent thing. I'm glad you did though, because I like a lot of the clever rhymes and the way your word choice changes the pace, puting the yearning into line 'Springtime will never come' and all those busy syllables later on illustrating the onset of Spring. Emotionally it might be 'Here Comes The Sun' which is my way of giving it a compliment. You did it - the joy and relief is there in the song and it moved me.
I thought overall that the verses in 'Prarie' were more emotive than the chorus, but that's true of a lot of songs. The verses tell the story and the chorus is a punctuation mark. It's a real song and a good story. I love the way that lines like 'We'll go dancin' at both bars' capture futility of small town life but at the same time people's determination to make a life there. For some reason I love the fact that the town only has two bars. That line says so much about the culture of the place, which brings me to a bigger point. I think these stories work because they're real stories from a real place. The audience can connect with that and see this world through your eyes. 'Wheat won't grow no faster watered down in tears' is fine writing in my opinion.
